DARIUS WELLINGTON, OF'BOSTON, MASSACHUSETTS.

Letters Patent No. 102,341, dated April 26, 1870.

IMPROVEMENT IN FAUCETS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, DARIUs WELLINGTON, of

Boston, in the county of Suffolk and State of Massachusetts, haveinvented an improved Valve-Cock or Faucet; and I do hereby declare thatthe following, taken in connectionv with the drawings which accompanyand formpart of this specification, is a description of my inventionsnicieut to enable those skilled in' the art to practice it.

'The invention relates particularly to the construction of that class ofvalve-cocks or faucets, each of which has a -reciprocating valve whichis forced down against the valveseator drawn up therefrom, by therotation of' a screw-threaded spindle, which spindle rotates withoutendwise movement, while the valve reciprocates without rotativemovement.

Heretofore these valves have generally been chambered or formed withnut-threads, which construction is objectionable.

In my faucets or valvecocks, I make the valve solid and square orprismatic, in cross section, and with a screw cast with it, andextending up f'rom its top into the main spindle, which is made tubular,and with a nut-thread, with which the thread on the valve-spur dleworks, rotation of the valve spindle by means of' the handle upon theend thereof, forcing the screw and its valve down towardi the seat, orup therefrom, in accordance with the direction of rotation of' thehandle.

This construction constitutes the first part of my invention.

The valve-spindle is formed with a flange, which fits and slides in thecylindrical part of the chamber of the faucet, andaround the top of thefaucet is a screw-thread, over which the cap screws, the main spindlepassing through the cap.

Within this cap is afiexible washer or packing ring, made slightlylarger in diameter than the inner diameter of the cap, or so as to fitclosely to the cap-ring, and also with a center-hole slightly smallerthan the spindle, so as to hug closely to the spindle.

'lhe spindle-hole through the cap is made large enough for the passageof the main part of the spindie, but at and adjacent to the top of thecap the spindle is made smaller than the cap-hole, and between the topof the cap and the handle are a spring and a sleeve, so arranged that byrotation of a screw at the top of the spindle, the spindle may be drawnupward to compress the flexible washer more or less tightly against theunder surface of the cap, also forcing the washer or packing-ringinwardly against the spindle at the center, thereby tightening the jointaround the spindle; this method of tightening the joint. between thespindle and cap constituting part of my invention.

The drawings 'represent a valve-cock orv faucet embodying myimprovements.

A shows a sectional elevation of the same.

B shows the valve in elevation, and the body of the faucet in section.

C is a bottom view ofthe valve and cap. v y

a denotes the body of the faucet, made with two tubes. b c, leading fiomthe valve-chamber d, either of which tubes may form the inlet, and theother the outlet passage. Y

Between the two tubes, or between the chamber d and tube c, is thevalve-seat or partition e, having through it the valve-opening jthevalve l9v shutting down upon this, seat and closing the valve-passage,as

seen at A, or rising from said seat, to allow flow of water through thevalve-opening, as seen at B, the valve-face being provided with asuitable packingdisk, h.

From the top of the valve, a screw, t', extends, the

screw and-valve being made in one piece, as seen at A. The main orvalve-operating spindle is seen at k,

`said spindle extending through the cap l, and rotating axially therein,the spindle being kept from upward movement by a fiange, m, and fromdownward movement by devices intervening between the handle n, attachedto the top of the spindle, and the top of' the cap.

This spindle is made tubular, and has a nut-thread, i

o, extending up into it, as seenat A, this thread corresponding with thethread ou the-screw t so that by' 'rotating the handle, the screw 'i israised or lowered, and the valve g thereby lifted from or forced againstthe valve-seat.

The cap l has a nut-threaded ring or fiange, p',

which screws down ,over a screw-thread, q, cut around the upper part ofthe faucet-cylinder, to attach thel apply the spindle vthat the xwashermay becompressedbetween the spindleffiange and the bottom of the caps,as follows:

The spindle above the cap is madeof' the same diameter as thespindle-hole through thecap, a distance of about the length of thespindle-hole, but above it is made smaller in diameter. Now by placingthe washer between the flange and the cap, the spindle is carried down,as seen at A, leaving a space through which the spindle can playupwardly.

\ the handle, as seen at A.

It will readily be seen that, by turning the screw, the valve-spindlemay be raised by the screw, and the rise of the spindle will compressthe washer between the flange and the cap, thereby enabling the jointbetween the spindle and cap to be made more or less tight,v ascircumstances may require.

The valve is made square or prismatic, in section,

as seen at C, and fits loosely and slides between corresponding walls ofthe valve-chamber, this formation preventing the valve from rotation,and dispensing with the employment of feathers or projections andgrooves for this purpose.

By casting the screw-spindle and valve in one piece, all expensevoffitting and connecting them together is obviated, as well as liabilityof the parts to loosen and become inoperative or imperl'ectly operative.

l I ela-inl, in combination with the ilexible washer rr and thevalve-spindle k,' having a flange,` m, that packs the washer against thecap, the screw lu, washer u, handle vn, sleeve s, and spring t, when thespindle is so formed, and t-lie sleeve s so arranged, that by turning upthe screw v the flange is tightened against the washer r, substantiallyas.described.
